In this paper, we analyze why merged firm sometimes produce only one product and sometimes produce two ones. We found the key reason for this depends on cost type of firms. If the cost of quality improvement is fixed, only one product will be manufactured, however, if the cost of quality improvement is variable, both products remain to be produced. In addition, we also analyzed the impact of merging on social welfare. We found both the consumer surplus and social welfare would decrease after merging. For this reason, the merging of duopoly with vertical product differentiation should be restricted by government.
